A must have for reef tanks By Acameron2on 7/16/2015

Acameron2 would recommend this product to a friend

Bought this starter kit so I can attemp to keep my parameters more stable for sps corals in my biocube, right after getting the dosage dialed in I bought a few acropora frags and so far I have great polyp extension and encrustation after a month of usage. Btw this kit is dummy proof, I've never dosed before this and now I can't imagine not ever dosing again judging by my results so far.

Just as others have stated, this 2 part starter kit is great! First time I dose in any of my tanks and the growth is amazing. Instructions are straight forward and with tips from their video, this has been a awesome purchase.

I'd never dealt with two part before. This makes it simple. Find the video, and you're set. Now I just need to remember to add them - guess I'll be buying dosing pumps soon.

The Best Way to Begin DosingBy Haroldon 3/26/2014

This package is great. It couldn't be easier to understand and use this product. No measuring required, just empty the package into the provided jug, add RO/DI water, and mix. Once you are done the BRS Reef calculator makes determining the amount to dose a breeze.

This is the best and a no brainer to mix, I was using continuum 2 part and of course they have no info available to the public. So I needed to switch and I already see a big difference in my sps.
Thanks BRS I'll be back for more.

Product Questions

If I'm doing a FOWLR setup, is this additive needed/required for that type of tank?

Question by: Paul on Jul 25, 2014 12:19:00 AM

Hi Paul,
It should not be particularly necessary. You may have an interest in maintaining calcium and alkalinity levels because coralline algae will consume them. Depending on the rate of growth your typical water changes may be sufficient though.

I don't understand why there is 1 Galloon of 2 part Magnesium mix and 3-20 oz of Magnesium.

Question by: David Smith on Mar 2, 2014 11:01:00 AM

Hi David,
They are just different sizes for different purposes. 20oz of magnesium solution is what is dosed when you finish a gallon of calcium and alkalinity. The 1g mix of magnesium is for adjusting your magnesium levels outside of the normal two part dosing schedule (like adjusting your salt mix to make sure it matches before doing a water change for example).

The BRS 2 Part Calcium & Alkalinity Starter Package is the easiest way to get started with the 2 Part Solution. The Calcium, Alkalinity, and Magnesium parts each come in pre-portioned pouches that can be quickly added to the included jugs and mixed with RO/DI water. No messing around with measuring cups. This starter package will help maintain Calcium, Alkalinity, and Magnesium parameters in the tank in easy once a day doses. Your corals will be healthier and grow faster. The 2 Part Solution can be automated using peristaltic dosing pumps.

Use the BRS Reef Calculator to calculate dosage amounts. For more information on how to use the 2 Part Solution click here.

Note: The starter package differs from the total package. The starter package comes with small convenient pre-portioned pouches. The total package is bulk packed containers of the same medias.
